Digital Terrain Model (DTM) of 1m the Autonomous Community of the Basque Country. Year 2017.

The 2017 Digital Terrain Model of 1m grid pitch reflects the bare surface of the terrain. This DTM, which originates from the DTM published in 2016 on the geoEuskadi portal, incorporates the changes in the terrain in urban areas observed in the Basque Government's 2017 10cm photogrammetric flight of urban areas and the changes in the terrain outside urban areas that have been updated with the 2017 LIDAR data. Improvements have also been made in those areas of the DTM where the point density of the 2008 and 2012 LIDAR data did not give a good definition of the relief in the generation of the DTM.
